摘　　要：目的　以磁共振显像技术为对照标准 ,探讨动态三维超声技术测量左室心肌质量的准确性。方法　 33例患者分别应用经胸 M-型、二维、三维超声心动图检查和磁共振检查测定左室心肌质量。结果　以磁共振测量的心肌质量为标准 ,M-型、二维和三维超声心动图测定的心肌质量与 MRI法测值的相关系数分别为0 .90、 0 .91和 0 .98(P均 <0 .0 5 ) ;配对 t检验表明 ,M-型超声法测定值明显高于 MRI心肌质量测定值 [(2 0 8.91± 6 4 .18) g vs(182 .97± 5 5 .0 8) g,SEE=12 .2 6 g,P<0 .0 5 ],而二维超声面积 -长度法 [(181.0 2± 5 9.6 7) g]和三维超声心动图法心肌质量测定值 [(181.83± 5 5 .4 7) g]与 MRI法测定值之间则无显著性差异 (P均 >0 .0 5 ) ,SEE分别为 8.91g、 4 .2 2 g。结论　以磁共振显像为对照标准 ,三维超声测量心肌质量的准确性显著高于Objective To explore the accuracy of left ventricular mass estimated by three-dimensional (3-D) echocardiography and to compare with MRI.Methods The study population consisted of 33 patients referred for MRI examination.Thransthoracic M-mode,two-dimensional (2-D) and 3-D were performed to calculate left ventricular mass.Results Left ventricular mass measured by MRI significantly and positively correlated with those by M-mode,2-D and 3-D echocardiography(r=0.90,0.91,0.98,respectively,P<0.05 for all),but there was significant difference in the left ventricular mass between M-mode echocardiography and MRI(P<0.01).Conclusions Compared with MRI calculations,3-D echocardiography was more accurate than M-mode and 2-D echocardiography for determining the left ventricular mass.
